摘要： An antenna device includes a helical antenna that radiates a circularly polarized radio wave in a direction of an axis S, in which the helical antenna is formed with linear conducting bodies each helically winding around the predetermined axis and adjacent linear conducting bodies are spaced a distance P apart. The antenna device further includes a director that is on the axis S, along which a radio wave is radiated from the helical antenna, at a position a distance X away from the helical antenna, the distance X being substantially equal to the distance P.

摘要： A reader/writer apparatus includes a tag search instruction receiving unit that receives a tag search instruction from a host apparatus. The tag search instruction includes a data read instruction and/or a data write instruction on the RFID tag. The reader/writer apparatus also includes a tag identification information requesting unit that transmits to the RFID tag a request for transmission of tag identification information uniquely identifying the RFID tag when the tag search instruction receiving unit receives the tag search instruction; and a data processing requesting unit that transmits a data read request and/or a data write request to the RFID tag identified by the tag identification information based on the read instruction and/or the write instruction when receiving the tag identification information transmitted from the RFID tag in response to the request for transmission transmitted from the tag identification information requesting unit.
